MOLD FOR CASTING SASH-VVEIGHTS.

SPECIFICATION forming part of Letters Patent No. 407,732, dated July 23,1889.

Application filed May 29, 1889. Serial No. 312,492. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD J owrrr, of South Pittsburg, in the countyof Marion and State of Tennessee, have invented certain new and usefulImprovements in Molds for Casting Sash-WVeights; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in molds for castingsash-weights; and it consists in the combination of the flask havingapertured metallic end pieces, the chills which are passed through theend pieces, the

gate, and the rods which hold the chills in position, as will be morefully described hereinafter.

The object of my invention is to produce a flask in which a number oftiers of weights can be cast at the same time, the weights all beingeither of the same size, or of two different sizes, as may be desired.

Figure 1 is a plan view of a flask which embodies my invention. Fig. 2is alongitudinal vertical section of the same.

A represents the wooden side pieces of the flask, andB the metallicapertured end pieces, which are secured thereto in any suitable manner.These end pieces have tiers of openings made through them, so that alarge number of weights can be cast at the same time, any desired numberof weights being cast in each tier. The openings through the metallicend pieces are just large enough to allow the chills O to be passedthrough them after the patterns have been withdrawn. Each pattern Dconsists of a solid cylinder of any desired size, and the patterns uponone side are provided with long projections G, which fit incorresponding recesses in the other patterns, as shown. Theseprojections pass through corresponding openings in the gate-pattern Hand form the passages from the central opening formed by the gate intoeach pair of molds. The patterns are provided with projections or stopsI, which strike against the metallic end pieces 13, and thus regulatethe distance that they shall extend inside of the flask. If it isdesired to cast all of the weights of the same size, then they willextend an equal distance into the flasks at each end; but if both lightand heavy weights are to be cast the gate will be moved beyond thecenter in the direction of the light weights, and the patterns of theheavy weights will be forced correspondingly farther inward. The chillsare made of cast-iron, and two are placed in each mold. The one O,whichis placed inside of the molds, forms the eye for the knot of thesash-cord,while the one which is passed through the end pieces forms theend of the weight. The flask is placed in position, and then the bottomtier of patterns are inserted and connected in the gate, as shown. Sandis then thrown in and rammed up, after which the second tier of patternsis rammed up in the same manner. Athird tier is now inserted, and so on.The patterns are then all drawn from each end of the flask, the gate isdrawn, the small eye-chills are then placed in the ends of the molds,and the end chills are then passed through the end pieces into the endsof the mold and in direct contact with the eye-chills. The melted ironis then poured into the gate, and which flows into each mold through theholes which are formed by the projections upon the ends of the patterns.The small gates, which connect with the large gate, are easily brokenoff, leaving a perfect weight. The end chills are then taken out of theend of the flask, which is then lifted from the sand. These end chills,while the casting is going on, are held in position by means of the rodsP, which pass laterally through the side pieces A, just beyond themetallic end pieces B, and which serve to prevent the weight of metalfrom forcing the chills outward.

Having thus described my invention, I claim The combination of theapertured side pieces A, the metallic perforated end pieces B, thechills which are passed through the en d pieces, and the rods passingthrough the apertures in the side pieces to hold the chills in position,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
